Definitions

  • the present invention relates to the positioning technology of user equipment (UE) of terminals, and particularly, to a method and apparatus for sending positioning information.
  • UE user equipment
  • the UE positioning method based on evolved cell identifier is supported.
  • the method is as follows: the location information of UE is estimated by way of the UE or an eNode B measuring the downlink or uplink wireless signal in combination with the identifier of the cell where the UE is located.
  • the positioning method based on E-CID also supports the approaches based on UE and based on eNode B, wherein the approach based on UE refers that the UE per se calculates its location information according to information such as the measurement result and the identifier of the eNode B and so on, then feeds back the location information to a serving mobile location center (SMLC) in the network; and the approach based on eNode B refers that the eNode B calculates the location information of the UE according to information such as the measurement result and its own identifier and so on and feeds back the location information to the SMLC.
  • SMLC serving mobile location center
  • the information sent by the eNode B to the SMLC includes the timing advance information of the UE, the angle when the uplink signal of the UE arrives at the eNode B, and the measurement result of the uplink signal of the UE.
  • the existing protocols do not support that the location information of the UE is reported to the SMLC, which is equivalent to not supporting the positioning of the UE implemented by the eNode B.
  • the main purpose of the present invention is to provide a method and apparatus for sending positioning information so as to accurately position the UE by eNode B and report the location information to the network side.
  • the step of positioning the user equipment comprises:
  • the location information of the user equipment or the location information of the eNode B is carried in the positioning information between the eNode B and the SMLC.
  • the positioning information comprises timing advance information of the user equipment, an angle of arrival and the measurement result of uplink signal of the user equipment.
  • network elements where the timing advance information of the user equipment, the angle of arrival and the measurement result of the uplink signal of the user equipment in the positioning information are located are null.
  • the location information of the user equipment or the location information of the eNode B is carried in specific information which is newly set.
  • the eNode B when the location information of the user equipment is carried in the specific information which is newly set, the eNode B will no longer transmit positioning information to the SMLC or the transmitted positioning information is null.
  • An apparatus for sending positioning information comprises:
  • the positioning unit includes:
  • the transmitting unit includes the location information of the user equipment or the location information of the eNode B in the positioning information between the eNode B to which the user equipment belongs and the SMLC.
  • network elements where timing advance information of the user equipment, an angle of arrival and the measurement result of uplink signal of the user equipment in the positioning information are located are null.
  • the transmitting unit includes the location information of the user equipment or the location information of the eNode B in specific information which is newly set.
  • the transmitting unit will no longer transmit positioning information to the SMLC or the transmitted positioning information is null.
  • the eNode B can also report the location information of the UE or its own location information to the SMLC, thereby achieving the positioning of the UE by the eNode B.
  • the present invention is a remedy for the existing UE positioning approach, and its implementation is simple and applicable.
  • the basic concept of the present invention is: by way of extending the positioning information between the eNode B and the SMLC and adding an network element carrying the location information of the UE or the location information of the eNode B, the eNode B can also report the location information of the UE or its own location information to the SMLC, thereby achieving the positioning of the UE by the eNode B.
  • the present invention is a remedy for the existing UE positioning approach, and it utilizes the existing positioning information to send the location information of the UE, and the implementation thereof is simple and applicable.
  • Step 101 the SMLC decides to position the UE by using the uplink E-CID positioning method and to adopt the approach based on eNode B.
  • Step 102 the SMLC sends a positioning request to the eNode B.
  • the eNode B here is an eNode B currently serving the UE.
  • Step 103 after receiving the positioning request of the SMLC, the eNode B measures an uplink wireless signal of the UE.
  • the measurement items include at least one of carrier signal strength indicator, reference signal received power and reference signal received quality.
  • Step 104 after obtaining the measurement result of the wireless signal of UE, the eNode B calculates the location information of the UE according to the measurement result and its own geographical location information. In particular, the eNode B determines the distance from the UE to the eNode B according to the angle of arrival of the uplink signal of the UE (i.e.
  • Step 105 the eNode B sends the location information of the UE to the SMLC.
  • the eNode B includes the location information of the UE in the positioning information between the eNode B and the SMLC, however, a network element carrying the location information of the UE is not set before the positioning information; in the present invention, the positioning information is extended and a network element carrying the location information of the UE is added, as shown in Tables 1 and 2, in which the italic portion "UE location information" and "eNode B location information" are network elements newly added in the positioning information.
  • the UE location information includes latitude, longitude and altitude information and so on, and it is determined by the eNode B according to the above mentioned measurement result.
  • the eNode B location information includes information such as geographical coordinate and so on, and the location information of the eNode B determines the location information thereof when setting the eNode B, and it can be obtained by way of the configuration information of the eNode B.
  • the positioning information further includes the timing advance (TA) information and angle of arrival (AoA) of wireless signal of UE, and it further includes the measurement result information of the wireless signal of UE (E-UTRA Measurement Result List), which includes ECGI or physical cell ID information, carrier received signal strength indicator (RSSI), reference signal received power (RSRP) and reference signal received quality (RSRQ).
  • TA timing advance
  • AoA angle of arrival
  • E-UTRA Measurement Result List which includes ECGI or physical cell ID information, carrier received signal strength indicator (RSSI), reference signal received power (RSRP) and reference signal received quality (RSRQ).
  • RSSI carrier received signal strength indicator
  • RSRP reference signal received power
  • RSSQ reference signal received quality
  • E-UTRA Measurement Result List - Evolved Cell Global Identifier (ECGI) /Physical Cell ID - E-UTRA carrier RSSI - Reference Signal Received Power (RSRP) - Reference Signal Received Quality (RSRQ) Table 2 Information eNode B location information(e.g. geographical coordinate) Timing Advance (TA) Angle of Arrival (AoA) E-UTRA Measurement Result List: - Evolved Cell Global Identifier (ECGI) /Physical Cell ID - E-UTRA carrier RSSI - Reference signal received power (RSRP) - Reference Signal Received Quality (RSRQ)
  • the location information of the UE can also be included in the following information structures, as shown in Table 3: Table 3 Information eNB based SMLC based UE location information(e.g. LatitudelLongitudelAltitude, together with uncertainty shape) Yes No eNode B location information(e.g. geographical coordinate) No Yes Timing Advance (TA) no Yes Angle of Arrival (AoA) No Yes E-UTRA Measurement Results List: No Yes - Evolved Cell Global Identifier (ECGI) /Physical Cell ID No Yes - E-UTRA carrier RSSI No Yes - Reference signal received power (RSRP) No Yes - Reference Signal Received Quality (RSRQ) No Yes
  • the information structure in Table 3 means that if the UE positioning approach based on eNode B is used, the eNode B only sends the location information of the UE, and other information such as the measurement result of the uplink signal and so on may no longer be sent; when the eNode B sends the location information of the eNode B but does not send the location information of the UE, other information in the original positioning information also needs to be sent to the SMLC, because the determination of the UE location information cannot be implemented only by the location information of the eNode B, and other information is also needed, such that the accurate location information of the UE can be determined.
  • the location information of the UE can also be carried by way of a new information format which is specially set, i.e. information is newly set between the eNode B and the SMLC to transmit the location information of the UE, and the original positioning information in the system is still sent normally.
  • a new information format which is specially set, i.e. information is newly set between the eNode B and the SMLC to transmit the location information of the UE, and the original positioning information in the system is still sent normally.
  • the information structure shown in Fig. 3 when the location information of the UE is carried in the specific information which is newly set, the information in each network element in the original positioning information can be null, i.e. any information in the original positioning information will no longer be sent. If the location information of the eNode B is carried in the specific information which is newly set, the original positioning information has to be sent and the information of each network element therein has to be carried.
  • the UE location information and the eNode B location information in the present invention can be sent to the SMLC simultaneously, and the UE location information is finally determine.
  • the present invention is a remedy for the existing UE positioning approach, in which the existing positioning information or newly set specific information is utilized to send the location information of the UE, and the implementation thereof is simple and applicable.
